Hi.

Sometimes I see dropped ICMP message in Windows firewall logfile. My guess it's somthing to do with MediaPortal heartbeats. Which is right configuration for ICMP setting in Windows Firewall?

Tv-server is at 192.168.1.21 and client on 192.168.1.27:

2008-11-03 23:08:54 DROP ICMP 192.168.1.21 192.168.1.27 - - 96 - - - - 3 3 - SEND

After some study of Windows firewall log theory and ICMP protocol I discovered that the "3 3" stands for:
ICMP Type 3: outgoing Destination unreachable
" Code 3: Port unreachable error. When the designated transport protocol (e.g., UDP) is unable to demultiplex the datagram but has no protocol mechanism to inform the sender.

Indeed sometimes I have problems with connecting client to a TV stream (UDP?) from server. I can connect still to command port 31456 on server (I opened this port in windows firewall) and change channels, but tv streams are then not connected to. In that case I have to restart Mediaportal on client pc to make it work again.

I can check option in control applet Window Firewall - tab Advanced - ICMP settings - Allow outgoing destination unreachable. At the moment only Allow incoming echo request is checked which is by default I guess..
